CastleFlexx is a collection of patented health and recovery inventions. USA Made. USA Owned. Established to heal in 2022.A note from inventor Dan Castle:My goal was to change how chronic pain was being treated.This would require that I design a solution which could achieve1) Toe Dorsiflexion since the plantar fascia activates the entire posterior chain when its pulled back and engaged unlike with straps and bands which leave the muscle groups in the leg inactive2) Relaxing natural grip for longer stretch sessions, no more rope burn please!3) A more practical, convenient, and financially responsible solution that would target the ROOT cause of the chronic pain.I began testing Castleflexx and after just a few days everything changed for me. I felt a release in my back I hadn’t felt before. Shortly thereafter, I felt noticeable improvement in many other areas. For example, I stopped getting plantar fasciitis completely. GONE. After a few months of using CastleFlexx for 8 to 16 minutes a day, I began to feel better, move better and even look better. My wife Carly, who had also begun using CastleflFlexx, experienced significant improvement and no longer complains about her hip pain and sciatica. Life just got better for both of us.I hope our device which has a less than 2% return rate and is made in the USA helps you too!Dan Castle

I have actually purchased 3 castleflex apparatus (2luxuary and 1sport). The sport stays in my suitcase so I always have it available while the other 2 are in 2 separate locations. I started primarily trying to loosen my hip-knee-ankle chain but have found that my back and shoulders have greatly benefited from the leg routines. I sleep better with less pain and stiffness throughout the day. I know it looks gimmicky but I assure you that the Castleflex is the real deal (and believe me I have tried most everything!) and would wholeheartedly recommend it to anyone with joint or muscle pain.

Te castle flex is too heavy for me to use…i was unaware that when ordering great construction of the item though! Not for older Who have major back pain and also not for women whi are older and who have osteoarthritis.

Fast, fair, and courteous support but more importantly and amazing product. Very high quality and easy to use, makes stretching fun and effective. The heat is nice, but a bit hot for a longer strentch (5 mins or more). Wish it had levels, but it’s convenient to turn off during a stretch. Last point is sizing, if your flexible, you need less length which can offset your height.
